    Subject[PATCH 5.15 325/917] perf/x86/intel/uncore: Fix Intel SPR M2PCIE event constraints
    Date
    From: Kan Liang <kan.liang@linux.intel.com>

    [ Upstream commit f01d7d558e1855d4aa8e927b86111846536dd476 ]

    Similar to the ICX M2PCIE events, some of the SPR M2PCIE events also
    have constraints. Add the constraints for SPR M2PCIE.

    Fixes: f85ef898f884 ("perf/x86/intel/uncore: Add Sapphire Rapids server M2PCIe support")
